Did you know that every 15 minutes or so the giant dragon perched atop Gringotts Bank will actually breathe fire? That's right, you'll first hear a loud noise and then the fire breathing will ensue shortly. The Diagon Alley expansion has been completed at Universal Studios Florida and features a restaurant and several "signature shops". Reports indicate that these will include The Leaky Cauldron, Ollivanders Wand Shop, Weasleys' Wizard Wheezes, Borgin and Burkes, Madam Malkin's Robes for All Occasions, Wiseacre's Wizarding Equipment, and Florean Fortescue's Ice Cream Parlour.

Inside Wiseacre's Wizarding Equipment, if you looks close enough, you'll see a microscope that was used by Bill Weasley in the pre-show portion of the Gringotts ride. It's sitting on his desk.

2. Gringotts Goblins
